Draft 1966-2010 Results Available For Review

The 1966-2010 summary analysis is available for review at this link. We welcome comments on the analysis and presentation. A final version will replace this website after 29 February 2012.
Most Recent Update: 23 March 2011.

This website presents population change information for more than 400 species of North American birds, as estimated from the North American Breeding Bird Survey. Estimates of trend (interval-specific estimates of population change), annual indices of abundance, and maps of abundance and population change for these species are presented for a variety of regions.

Please Note:

The 1966 - 2009 analysis results present the first implementation of a hierarchical model analysis of Breeding Bird Survey data. The hierarchical model analysis has been described in the peer-reviewed literature, and a comprehensive comparison of hierarchical model results with results from the route regression method used in earlier summaries is available at this link . These results have been reviewed, but we greatly value your opinions about the new analysis and results. Remember the disclaimer!, and please let us know about errors or other issues that limit the use and value of this site.

We recommend that users consult the help files for information regarding the estimates, estimation procedures, and the presentation of results. Presentation of the hierarchical model results differs slightly from earlier summaries. Details regarding these changes and other innovations in the Results and Summary Website are available at this link .


General Information


Survey Results

Species Groups: Analysis of Change for Species Groups
Summary information on population change by region and time period

Interactive Species Trend and Indices Program
This program allows you to display trends for 2 time intervals, by species. Indices are provided as links from the species names

Interactive Regional Trend and Indices Program
This program allows you to display trends for 2 time intervals, by region. Indices are provided as links from the region names

Comparative Analysis

Comparative analysis
Species-specific comparison of regional results from hierarchical modeling to estimating equation results. The comparative analysis provides results for the 1966-2008 interval.

Analytical Tools

Interactive Route Data Summary
This program provides access to all information, for any species, on any BBS route. (Updated only to 2007) New:For US routes, we now provide summary information on remotely-sensed habitat data.

Interactive Hierarchical Model Trend and Annual Index Analysis
This program allows you to estimate population change for any species and time interval (1966 - 2009), in any region covered by the BBS

Program Comdyn
This program is for estimation of species richness from BBS data using capture-recapture based estimation procedures.
